Welding of Gantry Crane Rail
Welding of Gantry Crane Rail
(OP)
Dear Colleagues,
I would to know how to weld a square bar made of SM45C (equiv. to ASTM A29-1045). What are the filler (TIG) or electrodes (SMAW) to be used if we will conduct repair welding? What is the required preheat temperature and if required PWHT?
Thank you.

Ofcourse, without knowing the complete situation (I assume the bar is continuously supported), it's hard to give a definitive suggestion, but the above should show you the general direction.

Remember, if this weld fails and the crane falls down what will you say to the prosecuting lawyer in court - I got told it was OK on an internet forum !
