Fabrication Methods and Techniques

Electrode Welding

Nearly all weldable materials can be welded with stick electrodes, e.g. structural steel, boiler steel, steel tubes, cast steel, stainless steel, and hard facing steel. Electrode welding is simple and safe. The compact devices are easy to handle and transport. Since no gas is needed welding can be performed outdoors, even in wind. Electrode weld machines are used in all lines of business, from industry through to craftsmen.

MIG MAG Welding

MIG/MAG welding is the most popular welding method nowadays on account of its enormous advantages. The welding speed, minimum reworking and low distortion ensure high efficiency. The great weld seam strength, excellent thin-sheet properties and simple and safe handling with steel, aluminium and stainless steel make the method universally acceptable.

MIG Brazing

Called MSG (Metal Shielding Gas) brazing according to international standards –is a hard soldering procedure. MIG Brazing offers clear advantages for the joining of galvanised sheets compared to MIG MAG welding. The soldering seam features a high corrosion resistance and enables easier surface treatment. There is minimal distortion, even on very thin sheets, due to the low heat input. Galvanised thin sheet is used in the automotive engineering and building industries, in air-conditioning technology, household appliances and in the furniture industry. MIG brazing is ideal for these applications.

TIG Welding

With the TIG method (Tungsten Inert Gas) the electric arc burns between the non-melting tungsten electrode and the work piece. The advantages of TIG welding are that its easy handling and good control over the arc enable very comfortable and clean working. The low oxidisation of the work piece, small welding zone, omission of fluxing agents and non-spattering arc ensure clean, precise seams with no slag inclusions and no reworking.

Welding Best Practices

D. R. Welder will review current welding practices and advise on how to achieve improvements in quality and speed of production including advice on design changes, where appropriate. In a recent example a company producing brackets for retail display was taking 5 ½ minutes per unit and this was reduced to 10 seconds simply by changing the design of the brackets

Welding procedures

Increasingly customers require evidence of best practice and appropriate welding procedures.D.R. Welder can provide you with the necessary knowledge on how to construct accurate and comprehensive welding procedures

Calibration of Welding Equipment

Welding machine calibration is, of course, an absolutely essential aspect of welding procedures. D.R. Welder has vast experience and can include this service as part of a full consultancy or provide it as a stand – alone services

Non Destructive Testing

Non Destructive Testing can be useful to your establishment to give you confidence that your welds and the processes that you use are the best for your business. D.R. Welder is fully trained in all aspects of N.D.T. (Non Destructive Testing) including dye penetrant.

Most contracts insist that 10% of the finished product is subject to M.P.I. (magnetic particle inspection )and macro- examination. A photographic record is supplied by Dr Welder as standard practice.

Coding to BSEN 287/1

Are you being asked to work to BSEN 287/1, Dr Welder can visit you at your premises and arrange to code your welders, the results of the test in most cases can be returned in two weeks. D.R.Welder can provide a full coding service which is an essential requirement of an ever- growing number of customers.
