metals of different thicknesses

[Tim135]

I am going to modify a luggage rack for my dual purpose motorcycle by moving the turn signal brackets inward. The rack appears to have been made with tubing that is about 16-18 gauge. The pieces I will be installing to hold the turn signals will be either 16 ga or 1/8" steel. I need a little bit of stiffness so the bracket won't bend in a fall on the trail (I have been known to do that occasionally). What would be the best technique for welding two pieces of different thicknesses together? Thanks , Tim. Also to Rocky D., I took your advice and switched to .035 wire and it really made a difference. Here's a fillet weld on 1/8" scrap

what size wire were you using before ? and what kind of welder are you using ?

When welding on steels of different thickness always keep heat directed more so on the heavier gauge and wash onto the thinner one.

Really nice, Tim! Looks like you got it! :)

Jack, I am using a Hobart Handler 135 and was using .030 flux core wire. Now I am using .035 flux core wire.:)

Thanks, Rocky. I will submit some lap and butt welds later on for your perusal, Tim.:)

You know, I really should learn to put all my replies in one post, but I'll get it eventually. Jerry, thanks for the advice, Tim.
