I have chassis repairs to a Landrover to do - if I can get my skill level up.
Here are some pictures of a practice lap joint using old chassis rail. It's about 2.5mm thick. The welder is a SIP turbo mig 150 using co2 and 0.6 wire.
After much knob twirling I have settled on full current setting and lowest wire speed. This is no doubt wrong but faster wire speed was getting me nowhere.
Maybe I should be using 0.8 wire?
I have problems getting the balance between melting the overlapping steel and not penetrating the bottom steel.
I'll be testing the strength of this weld tomorrow by setting it on blocks and driving over it!!
Any help and advice greatly appreciated. The site has already been a great help.
