Pressure riveting and energy storage welding

What is a vertical Weld?

Vertical welding is done in a vertical line, usually from bottom to top; however, on thin material downhill or downhand welding may be easier. The overhead position is the most difficult position. Because the weld metal flows downward, this position requires considerable practice on your part to produce good quality welds.

Which power supply should be used in a submerged arc welding process?

Because SAW is generally a high-current process with high-duty cycle, a power supply capable of providing high amperage at 100 percent duty cycle is recommended. The submerged arc welding process utilizes the heat of an arc between a continuously fed electrode and the work.

What is a welding rod?

The term welding rod refers to a form of filler metal that does not conduct an electric current during the welding process. The only purpose of a welding rod is to supply filler metal to the joint.

What is the depth of penetration in welding?

The smaller the root opening, the greater shall be the angle of the bevel. Depth of Penetration - The depth by which the arc melts into the plate is called the depth of penetration. As a very rough guide, the penetration is about 1 mm per 100A and in manual welding the current is usually 150 – 200 amperes.

How does a submerged arc welding process work?

The submerged arc welding process utilizes the heat of an arc between a continuously fed electrode and the work. The heat of the arc melts the surface of the base metal and the end of the electrode. The metal melted off the electrode is transferred through the arc to the workpiece, where it becomes the deposited weld metal.

What is arc welding?

The arc is a continuous spark formed between the actual work and an electrode (stick or wire) when a large current at a low voltage is discharged between the electrode and the base metal through an ionized column of gas. The resistance of the air or gas between the electrode and the objects being welded, changes the electric energy into heat.
