Welding Activities Meaning

The defect may differ from the desired weld bead shape size and intended quality. A weld can be defined as a coalescence of metals produced by heating to a suitable temperature with or without the application of pressure and with or without the use of a filler material.

Welding Defects can be defined as the irregularities formed in the given weld metal due to wrong welding process or incorrect welding patterns etc.

Welding activities meaning. It is a type of fusion welding process which uses an electric arc for supplying necessary heat to join the base metals and the filler metals. The heat may be supplied by electricity or by a gas flame. Welding is a joining process in which metals or sometimes plastics are heated melted and mixed to produce a joint with properties similar to those of the materials being joined.

Arc welding is a type of welding process using an electric arc to create heat to melt and join metals. The completed welded joint may be. MIG stands for metal inert gas though it is sometimes called gas metal arc welding GMAWIt is a quick process that involves the filler metal being fed through the wand while gas is expelled around it to shield it from outside elements.

In this process the conductive base plate is connected to one terminal of the power source and the electrode to another terminal. Gas welding with oxygenpropane flame Oxyhydrogen welding. Welding is usually used on metals and thermoplastics but can also be used on wood.

A power supply creates an electric arc between a consumable or non-consumable electrode and the base material using either direct DC or alternating AC currents. Welding is a process of joining similar and dissimilar metals or other material by application of heat with or without application of pressure and addition of filler material.
