The welding transformer - converts 'standard' mains electricity to high-amp power. The negative lead is attached to the piece of work, and the positive to the welding 'gun'. Touching the welding electrode (from the gun) - completes an electrical circuit - making an 'arc' with enough power to melt the metals together.
Transform mere garment into a work of art
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
In Pressure Welding the parts(work pieces) to be joined are heated only up to the plastic state and then fusedtogether by applying the external pressure.the two different types of pressure welding are:forge welding and resistance welding
Welding
The welding lens filters out much of the ultra violet light produced by welding.
It is the rate at which the welding rod is melted and deposited on the work being welded
If you work hard, you can Transform. To transform you need to diet and exercise.
Welders or steel workers use auto darkening and passive welding helmets .
This welding machine is useful to melt the metal at the end points. It converts 120-240 volt AC electricity to welding voltage. Thanks Artech Welders
I will be graduating this fall with my welding engineering degree. The majority of welding engineers will be making sure that a quality weld is established on a certain product. This is done by working with welders, training, qualifications, code work,..ect
Welding is done to weld materials by operating a welding machine. Many industries such as Shipyard, Robotics will be needing welding applications. The applications include extending a rod eor pipe, joining two materials etc. My brother is doing a welding course at Weldtech Training Inc at Ontario. He is very much fond of welding. It gives someones great opportunities to work in several fields.
The heat input in the case of Submerged Arc Welding (SAW) is higher than that in manual welding process. Reason is that the welding proceeds continuously while the work is rotated. In manual welding, it is controlled by the welder besides the time gap for changeover of electrode, relaxation by operator etc.
