260DET Posted August 19, 2008 Share Posted August 19, 2008 The blue anti roll bar pictured below has its arms welded to a hollow bar which should be spring steel. There are stick welding rods available which it is claimed are suitable for such welding, 303 I think is one. But rather than rely completely on just weld to hold such arms, I'm thinking of deforming each end of a hollow bar cold and having arms which have a matching hole which can be forced over the deformed part and then welded. Or is that overkill, keeping in mind that I don't have any heat treatment etc knowledge. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 19, 2008 Share Posted August 19, 2008 I'm wondering why you couldn't get a custom length circle track bar (commonly available here in the states), and then either machine a plate to fit the splines or make new arms with the tab to bolt to the rod end integrated into them. As to your original question, I wouldn't forsee any problem with welding as shown in the picture assuming the welding was done right. Of course I don't have any heat treating knowledge either...

johnc Posted August 19, 2008 Share Posted August 19, 2008 Funny. That picture above is of the Griggs GT40 SLA front suspension for a Fox body Mustang. I'm putting that exact front suspension on a Mustang right now. I wouldn't worry about a properly welded and heat treated part. Quote Link to comment Share on other sites More sharing options...
Flexicoker Posted August 19, 2008 Share Posted August 19, 2008 are you planning on heat treating after welding? In that case the weld alone should be fine. If you're not planning on heat treating afterwards... you need to. If you're making your own ARB, you don't have to make it out of spring steel. 4130 works great.

Guest remos111 Posted September 14, 2008 Share Posted September 14, 2008 I am wanting to do some welding on my 240 z frame. Does any one know the type of steel so I can choose the correct Flux core wire? Does the frame need to be heat treated after welding?
