the angle b/w the welding torch and the work for forehand welding (LEFTWARD WELDING) is 60-70 degrees.
Were as for backhand welding (RIGHT WARD WELDING) is 40-50 degrees.
The angle b/w the welding rod and the work is 30-40 degrees for both forehand and backwards welding.
So the answer is option C.

Answer is B.
FOREHAND WELDING:
The flame in the direction of travel and hold the tip at an angle of about 45 degrees to the working surfaces.
BACKHAND WELDING:
The welding tip should make an angle of about 60 degrees with the plates or joint being welded.
FOREHAND WELDING:
The flame in the direction of travel and hold the tip at an angle of about 45 degrees to the working surfaces.
BACKHAND WELDING:
The welding tip should make an angle of about 60 degrees with the plates or joint being welded.

Forehand welding:
The angle between torch and wp: 60-70 degrees.
Backhand welding:
The angle between torch and wp: 40-50 degrees.
The angle between rod and workpiece is 30-40 degrees for both forehand and backhand.
The angle between torch and wp: 60-70 degrees.
Backhand welding:
The angle between torch and wp: 40-50 degrees.
The angle between rod and workpiece is 30-40 degrees for both forehand and backhand.

The angle b/w welding torch & work in forehand welding is 60-70 wherein the back hand it is only 40-50.
So option C is correct, the angle b/w welding rod and work is 30-40 for both the cases.
So option C is correct, the angle b/w welding rod and work is 30-40 for both the cases.

Dear @Sandeep,
Here the angle between the torch and work piece not weld rod and work piece so the angle between the torch and work piece is 60-70 for fore head welding.
Here the angle between the torch and work piece not weld rod and work piece so the angle between the torch and work piece is 60-70 for fore head welding.

C is the correct answer.
Because rod angle for both techanic is same 30-40 degree.
But torch angle for leftward is 60-70degree.
And for rightward is 40-50 degree.

Fore- hand- torch make an angle with the plate is 60-70.
Back-hand- torch makes an angle with the plate is 40-50.
So, C is the correct answer.
Back-hand- torch makes an angle with the plate is 40-50.
So, C is the correct answer.

For Torch and rod.
In both cases forehand and backhand 30-40.
For Torch and work:
To forehand 50-60.
Black hand 40-50.
In both cases forehand and backhand 30-40.
For Torch and work:
To forehand 50-60.
Black hand 40-50.
