This is very common when welding frame rails, and is one of the reasons why some trucks only have three wheels in contact with the road. Try these.
1. document weld procedure very closely
2. repeat weld process exactly the same each time
3. as mentioned earlier try to alternate or balance welds...
Laminated steel and plastic was popular for a while on things like rocker covers and oil pans (remember those) So yes it does have deep draw capability. But as Greg mentioned the spot welds tended to look ugly. You basically had to squeeze the material hard enough that the steel made contact...
DReimer,
I know that you stated that your weld engineer looked at everything, but over the years I have seen so many complex problems turn out to be something so simple that you could cry. If you can make the problem disappear by changing a gun then that is where you need to spend 80% of your...

Stonecold is correct with the Pam spray preventing spatter. Most of the commercial anti spatter sprays are simlpy corn oil. The best plan is to optimize your weld parameters to prevent spatter, many of the new generation weld power supplies are light years ahead of...

this company uses compressed CO2 as a high pressure "sandblast" media with the resulting media vaporizing when done. Pretty cool!

The company I work for is quoting on parts for vehicles that will start in model year 2007. The life of these programs are 4 to 5 years. I hate to burst anyones bubble but if Henry Ford where to somehow time travel to the year 2012, he would recognize almost every part on the car as...
Hi imaz: I seem to recall that Miller used (rebadged) an OTC robot, there are several companies that sell/service older robots check out the attached link. As far as I know OTC is still in business and may be able to help.

I,m not sure where you are located, but up here in snow country many of the snow blowers (gas powerered augers for throwing snow) are equipped with small rubber track systems(see attached link)
Good Luck

Some of the "new" SUVs are now incorporating Advanced High Strength Steels (AHSS) Dual Phase Steels into their frame rail designs. These designs are as gdodd stated still stamped and spot/MIG welded together. For light truck frame design in north america many of the new frames are...
Savo:
I am assuming that you are resistance spot welding, and that you are trying to reduce the size of the spot weld depression on the "show" side. In the automotive industry this is done by putting a small "A" electrode on the bracket side of the weld and a large flat...
Hi Robo
Is your material a "coated material" ie galvaneal, galvanized, hot dip ? as the thickness of coating can have a significant effect on weld integrity.
As gdodd stated most car manufactures have different ratings applied to different areas of the vehicle. Spot Welds that are deemed safety welds (i.e. welds that join together stampings in areas that dissipate impact energy) will be grouped together. The standards for these welds are much more...
Hey tex if you want to check out the latest in "cosmetic" brush guards go down to your local Jeep dealer and check out the new Jeep Liberty ( the replacement for the Cherokee) yup that's a plastic brush guard. Must be for going through plastic forests. Then on your way back from Jeep...
Neotec is a hot-dip tin-zinc alloy coated steel. If you are not familiar with welding coated steels then you are in for a bit of a learning curve. First get in touch with your steel supplier (Corus) and demand that they send some one from there welding group over to put on a little seminar on...
Just to answer evelrod, Electric torque guns are used on many automated assembly lines when you need to to monitor torque and angle (number of turns) and then record this data.
In a previous life, I worked on a offroad/mining vehicles that ran two 12 volt batteries (24 v) for the starting circuit, and then ran 12 volts for the accessories/communications radios. I suspected that these where a compromise/oversight design based on what was available for the right price...
Hi Iank: What are you refering to when you say vibration welding?(i.e. what frequency) What types of materials are you looking to join? what thickness? If you can provide a little more info you can probably find someone with some background in that area.
