EXERCISE 26 : Pipe welding - 45° branch joint MS pipe
ø50mm and 3mm wall thickness in
flat position (OAW)
Objectives
At the end of this exercise you shall be able to
• prepare the development of pipe for 45° branch joint
• cut and prepare the pipes as per dimensions
• tack and complete the welding by manipulating the torch and filler rod.
Procedure for development of 45° branch pipe: Refer Fig 1. Draw a centre line AB.
Mark the points C, D, E and F taking the radius and the length of the given pipe with the centre line AB as
reference line.
On the line “CD” locate the position of the 45° branch pipe. This will be “G”.
Draw a 45° angle at the point “G”.
