Welding Advice? (Safety Chain & Cable Attachments)

On this thread:

(Safety Chains versus Cables)
http://www.airforums.com/forums/f464...ins-30021.html

on/about post 409 or 50 are links to a couple of types of safety chain attachments.

The thread begins with a dicussion of cable versus chain, and I have added several quotes on legal requirements. Prominent is FMCSA 393.70 which states, essentially, that

Of a pair of chains (or cables) EACH must be of a strength sufficient to handle the GVWR of the trailer. Same for each attaching end on the truck and trailer.

So, for my trailer that would be [4] each 8,000# points, and [2] Grade IV chains with hooks, etc.

The question here, specifically, is about how to specify the best possible welding on the trailer tongue and to the truck.

On other forums I have read things such as: "Ah, I think I'd use maybe stainless 310 rod. Or 312".

I have no experience to judge this with. Any good advice, or links to welding practices which educate would be gratefully received.

Thanks.

Are you going to do the welding yourself? I would make the first penetrating pass with an E6010 electrode and cap it off with an E7018. These are both mild steel welding rods.
If you're going to have a welding shop do this for you, I'm sure that this is what they will recommend.

No, I am no welder. I am willing to read to depth (basics and general practices) so as to help understand what a shop or an "expert" might recommend.

Your specifics are my beginning.

Stainless steel electrodes (rods) are typicaslly not as strong as carbon steel E60XX or E70XX series electrodes. It's a carbon content issue. A E6013 is a good "All Around" electrode. The numbers mean various things;

E = Electrode
60 = 60 ksi, or 60,000 lbs (strenght)
1 (rods) are gen

Oops...hit the wrong key...


E= Electrode
60 = 60 ksi, 0r 60,000 lbs (strength)
1 = All Position Electrode (Can be used for welding in all positions, whereas a 2 means flat position only)
The last digit = 0, 1, 3, 8, etc describes the chemical composition and defines certain electrode characteristics.

Thank you for the homework, gents. Now, what might YOU want to see to weld those attachments to your trailer tongue?

My chains are not welded. My rig has a 1/2"x 2" steel flat bar welded under the tongue tubes. The chains attach to the ends of the flat bar that extend out past the edge of each tube (approximately 2 inches).

The ends of the bar are radiused (rounded off) to remove sharp edges. My chains attach to each end of the bar using two high strength shackles that thread through holes in the flat bar.

The HeavyHauler is stored 100 miles from here or I'd post some photographs. PM me and I can send youa rough sketch.

Just a caution from past experience: Leave welding to the professionals. That is, those who have been well-trained in industry or have been to school. I've seen too many weld failures when the work was done by part-time, local body shop people.

I have no intention of being the welder. I have an interest in the subject, and wish to know enough to get the best service. Having visited at length with pipeline welders and one guy who traveled to nuclear plants all over as a welder made me realize that it is far from simple. Thanks.
