In backhand welding, the angle between the welding rod and the work is ________ as compared to forehand welding.
A. Same
B. Less
C. More
D. None of these
Answer: Option C
Solution (By Examveda Team)
In welding, the terms "forehand" and "backhand" refer to the direction and angle at which the welding torch or rod is held relative to the direction of welding.In forehand welding, the welding rod is directed in the direction of welding with a smaller angle (typically around 30° to 45°) between the rod and the workpiece.
In backhand welding, the rod is directed opposite to the direction of welding, resulting in a greater angle (typically around 45° to 70°) between the rod and the workpiece.
This greater angle in backhand welding allows better penetration and is often used for thicker materials.
Therefore, the angle between the welding rod and the work is more in backhand welding as compared to forehand welding.
This Question Belongs to Mechanical Engineering >> Workshop Technology
Back hand welding 40-50
Forehand welding 60-70
Answer is less
The question itself is very confusing. The question should instead be based on the direction of the weld rather than the work. For Backhand would be an acute angle and forehand would be an obtuse angle.
B
Forhand 60-70 degree, backhand 40-50
Answer is c)
Ans is (C)
In forhand welding angle 30°-40°
In backhand welding angle 40°-50°
