Good And True Welding Technique

Welding is one of the techniques of metal grafting by liquefying some of the parent metal and filler metal with or without pressure and with or without adder metal and producing continuous connection. Welding by the method known now, began to be known at the beginning of the 20th century. As a source of heat is used fire derived from the burning gas acetylena which became known as carbide welding. At that time has been developed electric welding but still starting to rare .

An electric arc weld or generally called an electric weld includes a process of connecting metal using electric power as a heat source. So the heat surnber on the electric weld is generated by an electric current arc, between the welding electrode and the workpiece. The workpiece is part of a series of electric current portable welding current. Electrodes melt together with the workpiece as a result of an electric current arc.

Equipment needed in the welding process include:

  1. Main Equipment

– Welding machine

– Electric current: AC / DC

– Holder / tang electrode / clamp electrode/ brazing

– Men mass / Plek mass

– Las cable: electrode cable / mass cable / power cable

  1. Safety Equipment

-Weld mask = protect the eyes from welding rays

– Mask / blower suction = protector of the nose to avoid welding smoke

– Apron / chest protector

– Special gloves

– Protective shoes

  1. Equipment Help

– Pliers

– Steel brush

– Crust hammer

– Welding table

– Grinding machine

Welding method:

Know the slope of the electrode against the holder / clamp of the electrode

The position of the electrode slope of the workpiece

The position of the body should be as comfortable as possible and relax

The electrode slope (70/80 degrees) and weld direction follow the slope of the scratch electrode.

Position of welding mask for work safety (mandatory in use)

The material to be welded, should be sealed if possible should be pressed, so welding only thin enough and not patching. If the material is thick enough, for a neat welding needs to be made pieces / cats along that will be welded with digerinda.If you need more information you can visit canadian welding company.

Setting the amount of current is required. Small currents cause the welding wire is not lit, welding results are not mature / strong and uneven. The overcrowded currents resulted in the welded material being welded, the welded became rough and when it was cold mletek2 due to too high temperature. As ancar2 to 1 mm welding wire required a current of 30 ~ 40 Ampere.

Should avoid a sudden cooling after welding (watered) as some materials will crack.

If we weld in a way slowly and carefully then the welding will be good. But if we weld in a quick way, in a hurry then the results of his work is not good, because in welding techniques required prudence, thoroughness, and tenacity for the work And welding can be done well.
