Setting Up for Alu Welding

Setting Up for Alu Welding

Aluminium welding can be frustrating until you de-bug your welder. The wire is much less stiff than steel wire so is prone to crumple after the roller. An oversized tip and plastic wire liner are required together with other tweaks to your welder.  http://usedweldingmachines.blogspot.com/

 How to weld aluminium (turns out it's not so bad).

Aluminium very quickly forms an oxide layer which needs to be removed before welding. From there the welding process is tricky because of the rather narrow window between melting the aluminium and blowing holes. http://usedweldingmachines.blogspot.com/

MIG Brazing

MIG brazing is a relatively new technique that tends to be used by automotive manufacturers on modern steels that can't really be welded using conventional techniques. http://usedweldingmachines.blogspot.com/

Cast Iron MIG Welding

Cast Iron MIG Welding
A very useful application of MIG brazing wire is in the repair of cast iron. Braze is much softer than steel filler wire so reduces problems with cracking of the cast iron. http://usedweldingmachines.blogspot.com/

This page describes a traditional studding technique as well as the use of braze to join a cast iron gear casing, and discusses alternative methods thaCast Iron MIG Weldingt could have been used to join the casting.

Replacing a floor panel

 This is from my Renault Gordini project. The page covers removing the old floor pan, preparing the new panels, and ways to prevent distortion when welding thin panels.

Repairing a suspension mounting

Repairing a suspension mounting
Another from the Gordini project. Intended to be the most complicated way to repair anything ever seen on the internet. But it was fun to do even in the cold winter weather. http://usedweldingmachines.blogspot.com/

A few thoughts about DIY welding and suspension alignment along the way.
