Ali and sons Marine Engineering Welder Interview Questions and Answers

Welding is a process of joining two or more pieces of metal together by melting and fusing them.

• Welding involves using heat to melt the base metals and adding a filler material to create a strong bond.

• Common types of welding include MIG, TIG, and stick welding.

• Welding is used in various industries such as construction, automotive, and manufacturing.

• Examples of welded products include bridges, pipelines, and metal sculp

Arc strike is a mark left on the base metal by an electric arc during welding.

• Arc strike occurs when the electrode touches the base metal before striking an arc.

• It can weaken the base metal and lead to defects in the weld.

• Arc strikes should be removed before welding to ensure a strong and clean weld.

• Examples: scratches, burns, or pits on the base metal caused by the arc.

Arc welding uses a consumable electrode, while FCAW welding uses a continuously fed wire electrode.

• Arc welding uses a welding power supply to create an electric arc between the electrode and the base material, while FCAW welding uses a tubular wire filled with flux to shield the arc.

• Arc welding is typically used for thicker materials and outdoor applications, while FCAW welding is often used for welding thick materials...read more
