Welding
1. On- road drawbar eyes are provided for welding into the drawbar by electric arc welding, preferably done under a protective gas shield. Welding must be performed by a person qualified to work on such equipment. Regulations may vary from state to state.
2. The steel of the drawbar has to be weldable, e.g. made of St 37-2 or St 52-3 or any other compatible weldable steel with a carbon content of less than 0.22%.
3. Remove all paint, grease and rust from welding surfaces. Heating up of drawbar eye to 200 - 250 Deg C before beginning to weld is recommended.
4. The drawbar eye must not be welded within a length of *mm measured from the middle of the drawbar eye access towards the back. This part should protrude out of the drawbar.
5. The welding should be exercised in one seam at a time only, in order to avoid overheating the surrounding space of the welding seam.
6. Carry the welding onwards to the direction of the drawbar eye access in one procedure.
7. All seams have to be laid in longitudinal direction of the drawbar eyes shaft. Never and by no means crosswire.
8. Each seam of welding should be set one by one diagonally opposite to the last one, so you maintain an even radiation of heat.
9. Cooling down of the welding should take place where the air is still; do not immerse into water or pour water over it.
10. If wanted, you can place slot welds through the lateral surface of the drawbars sectional steel. This is in order attach to the drawbar shaft to the drawbar additionally.
11. The thickness of the welding seams is to be approximately 8mm in full V- shape or half V-shape.
12. The thickness of the sectional connecting bars should be at least 8mm, better from 10mm - 12mm.
