Re: [MW:14219] Welding C45 (1045)

the information i gave you comes from notes i got when i did my cswip
level 2 welding exam .......i never came across welding a hi carbon
steal higher than .4 but this what the notes told me when you welding
a steel of a carbon content higher than .5 so get a second opinion
then....my bad
but when im welding steel of a carbon content of .3 to .4 this is what
id do..... Parts may be readily welded with all process if preheat,
interpass temperature controls, and post heat recommendations are
followed.

Use Low hydrogen Electrodes and appropriate filler wire.

Heat treating after welding may be applied
