Psn Construction Equipment Welder and Gas Cutter Interview Questions and Answers

Q1. How many Gases use in gas welding
Ans. 
There are typically two gases used in gas welding: oxygen and acetylene.
• Oxygen is used as the oxidizer to support combustion

• Acetylene is used as the fuel for the welding process

• The combination of oxygen and acetylene produces a high-temperature flame for welding and cutting

• Other gases like propane or natural gas can also be used in some cases

Q2. Diffrence between Arc welding & Mig Welding.
Ans. 
Arc welding uses a consumable electrode to create an electric arc, while MIG welding uses a continuous solid wire electrode and shielding gas.
• Arc welding uses a consumable electrode that melts to form the weld, while MIG welding uses a continuous solid wire electrode that is fed through a welding gun.

• Arc welding requires a flux to shield the weld pool from atmospheric contamination, while MIG welding uses a shielding g...read more

Q1. What is welding ?
Ans. 
Welding is a process of joining two or more metal pieces together by melting and fusing them.
• Welding involves using heat to melt the base metal and a filler material to create a strong bond.

• Common welding techniques include arc welding, MIG welding, TIG welding, and oxy-acetylene welding.

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

• Examples of welded products incl

Q2. What is the metal-to-tip distance?
Ans. 
The metal-to-tip distance refers to the distance between the metal being welded or cut and the tip of the welding or cutting torch.
• The metal-to-tip distance is crucial for achieving the desired weld or cut quality.

• It is typically recommended to maintain a consistent distance for uniform results.

• The distance can vary depending on the type of metal, thickness, and welding/cutting technique being used.

• For example, when MI...read more

Q3. What is the welding tip gauge
Ans. 
The welding tip gauge is a tool used to measure the size of the welding tip on a welding torch.
• The welding tip gauge is typically a small, handheld tool with measurements marked on it.

• It is used to ensure the correct size tip is being used for the specific welding job.

• For example, a welding tip gauge may have markings for sizes such as 0, 1, 2, etc.

• Using the correct size tip is important for achieving the desired weld

Q1. Which gass is use in mig welding
Ans. 
The gas used in MIG welding is typically a mixture of argon and carbon dioxide.
• Argon and carbon dioxide are commonly used in MIG welding to shield the weld from contaminants in the air

• The specific ratio of argon to carbon dioxide can vary depending on the type of metal being welded

• Other gases such as helium or oxygen may also be used in certain applications
