19 Dec Welding Positions

Welding is often done on structures in the position in which they are found. Techniques have been developed to allow welding in any position. Some welding processes have all-position capabilities, while others may be used in only one or two positions.

All welding can be classified according to the position of the workpiece or the position of the welded joint on the plates or sections being welded. There are four welding positions, which are illustrated below.Picture 1

Fillet Welding Positions – Fillet, groove and Surface welds may be made in all of the positions shown below.Picture 2

Flat Position Welding – In this position, the welding is performed from the upper side of the joint, and the face of the weld is approximately horizontal. Flat welding is the preferred term, but it is also referred to as a Down hand.

Horizontal Position Welding – The axis of a weld is a line through the length of the weld, perpendicular to the cross-section at its centre of gravity. Fillet Weld, Groove Weld, Horizontal Fixed Weld, and Horizontal Rolled Weld can all be done in this welding position.

Vertical Position Welding – In this position, the axis of the weld is approximately vertical. Vertical welding positions are shown in view C in the image above.

Overhead Position Welding – In this welding position, the welding is performed from the underside of a joint. Overhead position welds are illustrated in view D in the image above.

Pipe Welding Positions – Pipe welds are made under many different requirements and in different welding situations. The welding position is dictated by the job. In general, the position is fixed, but in some cases, it can be rolled for flat-position work.

06 Nov Types of Welds

Fillet Welds – A fillet weld joins two surfaces at an approximate right angle to each other. There are several types of fillet weld; a Full fillet weld where the size of the weld is the same thickness of the thinner object joining, a Staggered intermittent fillet weld refers to two lines of intermittent welding on a joint, and a Chain Intermittent fillet weld which refers to two lines on intermittent fillet welds in a lap joint or T where the welds are in one line.IMG_1582

Groove Welds – The second most popular type of weld, there are seven basic types of groove welds. The groove weld refers to beads that are deposited in a groove between two members to be joined. The type of weld used will determine the manner in which the seam, joint, or surface is prepared.

Seam Weld – A weld made by arc seam or resistance seam welding where the welding process is not specified. This term infers a resistance spot weld.

Surfacing Weld – These are welds composed of one or more strings or weave beads deposited on an unbroken surface to obtain desired properties or dimensions. This type of weld is used to build up surfaces or replace metal on worn surfaces. It is also used with square butt joints.

Plug Weld – Plug welds are circular welds made through one member of a lap or tee joint joining that member to the other. The weld may or may not be made through a hole in the first member; if a hole is used, the walls may or may not be parallel and the hole may be partially or completely filled with weld metal. Such welds are often used in place of rivets.

Slot Weld – This is a weld made in an elongated hole in one member of a lap or tee joint joining that member to the surface of the other member that is exposed through the hole. This hole may be open at one end or partially or completely filled with weld metal.

Flash Weld – A weld made by flash welding. Flash welding is referred to as a resistance welding process where fusion is produced over the entire abutting surface. Heat is created by the resistance to the current flow between two surfaces and by the application of pressure after heating is mostly complete. Flashing is accompanied by the expulsion of metal from the joint.

Spot Weld – A spot weld is a weld made by arc spot or resistance spot welding where the welding process is not specified. This term infers a resistance spot weld.

Upset Weld – An upset weld is a resistance welding process where fusion occurs progressively along a joint of over the entire abutting surface. The application of pressure before heating is required and occurs during the heating period. Heat comes from the resistance to the flow of electric current in the area of contact between the surfaces.

30 Sep 5 Most Common Metals Used to Fabricate Railings & Handrails

From building and reinforcing, to internal, decorative safety features: metal, in one form or another, plays an important part in the construction and fitting out of commercial properties. Handrails and railings are a case in point. Where some years ago, spindles and banisters would have been manufactured almost exclusively from timber, today they are more likely to be fabricated from stainless steel, mild steel, galvanised steel, aluminium or brass. They can also be designed to include a mixture of these materials. So, what are the pros and gatescons of these five different metals?

  1. Stainless Steel

If you’re looking for strength with a modern, stylish finish, either internally or externally, stainless steel tube ticks all the boxes. Although more expensive than mild steel, long term maintenance costs are reduced due to its high corrosion resistance. Stainless steel can be manufactured into a wide range of designs and styles, and fitted to brickwork, blockwork, concrete, timber and other metals to produce the contemporary, modern style required.

  1. Mild Steel

Mild steel is the cheapest option when it comes to guard rails and hand rails. Material costs are low, and the ease with which it can be worked make the construction element very cost-effective, depending of course, on the complexity of the required design. Under heavy-use circumstances, many architects choose to stipulate carbon steel for its added strength and durability. Although mild steel rails, hand rails and guards are usually powder coated or spray painted prior to installation, they are prone to corrosion and need regular inspection and maintenance to keep them at their best, especially if it is exposed outdoors.

  1. Galvanised Steel

Inside or out, unprotected steels are at the mercy of moisture either internally from moisture laden air, or externally from the weather. While painting will help keep much of this moisture away, galvanising all interior and exterior steelwork, whether walkways, stairs or hand rails, will provide years of protection. Standard galvanised steel can be a silver colour through to grey. Although galvanised steel can be painted, it requires the use of etch primers prior to painting, pushing up the manufacturing cost of the finished product.

  1. Aluminium

The biggest pro of aluminium is its weight, or lack of. While this lack of weight makes aluminium easy to handle and use, it is also a much softer metal compared to others, and prone to dents and scratches. When being used for handrails and safety railings, greater bare

Steel Framed Building | Dorset

29 Jun Why Cheapest Isn’t Always Best

Here atSteel Framed Building | Dorset, we pride ourselves on unbeatable prices with the highest quality and great customer care. We provide thorough research before supplying a quote to guarantee we provide quality materials and services at the best prices.

We all want the best value for money, but when it comes to metal fabrication, especially large-scale construction projects, the lowest bid doesn’t necessarily always provide the best value.

The lowest bid is often a result of a bidder’s mistake – scope items may have been missed, complexities may be underestimated or, worse case, craftsmanship may be undervalued. Any or all of these issues can lead estimators down a slippery slope.

Ultimately – and particularly when quality is at stake – the lowest bid almost always leads to other hidden costs that present themselves when it is too late to change.

Price quotes can vary for a multitude of reasons, and so can a company’s experience. When it comes to metal fabrication, and especially large-scale projects, you want the most qualified company for the job. A lesser-experienced company will often present a lower bid, and that inexperience is often reflected in lower-quality materials, shoddy workmanship, safety oversights and ultimately in the final project.

When it comes to choosing the one metal fabrication company that best suits your needs, there are five main factors to consider:

  • Capabilities
  • Experience
  • Quality
  • Methodology
  • Customer Service

15 Jun Welding Skills

Contact our fabrication experts today on 01202 882211 or email us at info@rowtecdorsetltd.co.uk to find out about the best steel fabrication Dorset has to offer.

Welding skills are classed as an art, it takes a lot of experience to get the right technique down. It is important to know what welders do and how they take steps to minimize weld distortion.

Welders cut, shape and join pieces of metal for both industrial and architectural projects. Key factors a welder should have are a skilful hand, a discerning eye, excellent Welding in hollow sectionmathematical skills, the ability to understand engineering drawings and, of course, knowledge about different types of metals and how to effectively operate different welding equipment and methodologies. High-end metal fabrication projects can be ruined by low-end welding skills, which is why, here at Rowtec, we take great pride in our work with our experienced welders.

Three of the most common welding fabrication processes used for metal fabrication are MIG, TIG and Stick Welding. The process used in a given project is determined by metal thickness, finish, location and application.

 

  • MIG welding is a great starting point for new welders and can be used with all types of metals and alloys. MIG welding is an arc welding process in which a continuous solid wire electrode is fed through the welding gun and into the weld pool, joining the two base materials together.

 

  • TIG is a more versatile welding process and requires a high level of skill. TIG welding can be sued to weld aluminium, copper, titanium etc; and even two dissimilar metals. This process is ideally suited to handling tricky welds such as S-Shapes, curves, corners or where the weld is going to be visible and where accuracy and finish is important.

 

  • As a manual welding process, Stick welding requires an even higher skill level. Stick welding, or shielded metal arc welding, has been around more than 100 years. Even though it’s an old welding process, it still plays an important role in manufacturing, with about 150 million to 200 million pounds of electrodes consumed in North America each year.

04 Jun Sheet Steel Fabrication and Ironworks

It may seem that sheet steel fabrication and ironworks have similar jobs, both are classed as highly skilled trades, but both have different skill sets and utilize different tools and materials. Usually, ironwork is more structural and sheet metal fabrication is more functional.

WorkshopIRONWORKERS

An ironworks or iron works is a building site where iron Is smelted and where heavy iron and steel products are made. An integrated ironworks in the 19thcentury usually included one or more blast furnaces and a number of pudding furnaces or a foundry with or without other kinds of ironworks.

There are three main types of ironworkers:

  • Structural ironworkers erect the framework of bridges, buildings, stadiums, amusement park rides, bank vaults and other large scale industrial metal projects according to engineer blueprints.
  • Ornamental ironworkers, or finishers, are responsible for the more architectural metal elements such as window frames, stairways, catwalks, railings, fencing, gates and building entranceways. This ironwork requires a high skill in arc welding.
  • Reinforcing ironworkers, or rodbusters, is to strengthen structures. These are the workers who place a tie rebar, and reinforce concrete footings, slabs, bridge frame work and building structures.

 

SHEET METAL FABRICATIONS

These skilled tradesmen frequently work in metal fabrication shops or at manufacturing plants and specialise in fabrication, installation or maintenance, but may also perform tasks in all three areas. There is a long list of fabrications that can be produced by sheet metal workers, including roofs and rain gutters, heating and cooling systems, handrails, and more. When fabricating using sheet metal you have to take into consideration the thickness, tensile strength, manufacturing method and quality. There are as many types of sheet metal as there are types of metal, most commonly used ones are aluminium, steel, stainless steel, zinc, copper and a variety of alloys.
