Welding according to the jasa pembuatan pintu besi di cibinong big Indonesian Dictionary (1994) "is joining iron by burning. Welding is one of the metal joining techniques by melting some of the parent metal and filler metal gone or without pressure and next or without supplement metal and producing a continuous connection. Welding similar to the method known today, became known at the beginning of the 20th century. As a heat source used ember from the combustion of acetylene gas which became known as carbide welding. At that time, electric welding had been developed, but it was yet rare.

Based upon the definition of DIN (Deutch Industrie Normen) welding is a metallurgical sticking to at the guide metal joint which is carried out in a melted or liquid state. From this definition, it can be supplementary elaborated that welding is a local relationship of several metal rods using heat energy. At this time, 40 types of welding have been used, including welding which is carried out by pressing two united metals hence that these two metals can be glued together.
Welding is one of the metal joining techniques by melting some of the filler metal taking into consideration or without pressure and taking into consideration or without new metal which produces a continuous connection. The scope of use of welding techniques in construction is entirely wide, including shipping, bridges, steel frames, pressure vessels, pipe pipes, pipelines and correspondingly on.

Welding techniques are sought after by some people who want to learn to weld. We can get these techniques in vocational or highbrow schools. However, for shadowy people who want to edit a welding workshop business, for example, they tend to not have epoch to laboratory analysis formally. Therefore, we will find the money for some welding tips that we wish can help us every in learning how to Weld Correctly.

The in imitation of is the exact welding procedure:

Clean the material to be welded. Use a hammer to descale the surface of the place to be welded. Use a steel brush for maximum results.
Place the material to be welded in the circulate provided. Be it using a workbench or just laying it upon the floor. get used to the density with the two materials. Use clamps if needed.
Place the welding machine addition on one allocation of the material to be welded. adjoin the electrode on the electrode clamping panel upon the welding machine. Install the face of the electrode according to the slant of the material. Usually there is a special place for the electrode viewpoint upon the electrode clamping pliers. Be it 90 degree, 30 or 40 degree perpendicular.
After the material is ready to be welded, slowly bring the tip of the electrode closer to the material to be welded.
The estrange amongst the tip of the electrode and the material to be welded greatly affects the air of the welding. If the make unfriendly is too far, there will be sparks in the manner of rain of fire spots. The welding process will not be perfect. If the separate from is too close, the flare will not burn properly. And there is not tolerable distance for the melting electrode. A fine turn your back on is one-eighth of the thickness of the electrode.
By using a protective mask or welding goggles, you can pay attention to the allowance of the electrode that has melted which unites the two materials physical welded. Slowly put on the electrode along the welded area.
Good results during the welding process can be seen when the welded surface is shaped subsequent to a tight and regular recognition that unconditionally covers the welded part.
When finished, clean the scale that covers the welded parts using a hammer. Check over whether there are parts that are not perfect. If it's not perfect, repeat the parts that haven't been put together well. In some cases, the welded material must be grinded another time if the welding is not perfect. But if it's not too fatal, we just need to weld the parts that haven't been welded perfectly.
