Welding Truck Chassis Rails

Allowed when joining the chassis rails and of course the welding quality is particularly important.

Welding truck chassis rails.

Welding on these frame rails carries a high risk factor since the heat treated frame rail material right next to the repair plate channel material might cause cracking due to the dissimilarity between the two. One concern with larger trucks is that their frame rails are sometimes heat treated to an exact specification to optimize their strength. A chassis absorbs a tremendous amount of stress that is distributed throughout the lateral beams and if the welding is not done correctly this can lead to chassis failure or wear and tear. This specification covers high strength low alloy hot rolled structural steel plates to use in truck frames crane booms rail cars and similar applications.

International chassis are presently manufactured with frame rails of. 2x big rig build off champions. The body will rarely fit neatly directly onto the chassis rails and so the sub frame is needed to make a durable. Whether a custom show winner or an oil field workhorse don t build your project on anything other than p g.

4 aum8101a modify or repair chassis frame and associated components single skin a single skin chassis consists of one channel pressing for each chassis rail. We work with our customers to stretch shorten truck frames to their specific needs. We use astm a656 grade 80 frame rails up to 36 in length. All rigid trucks have a body attached to the chassis rails.

The body such as a tray concrete pump or tank is attached to a sub frame that in turn is attached to the chassis rails. Each type has different repair procedures. Some trucks are designed with rivets in the bottom flange of the chassis rails. The frame rail material can be determined by inspecting the frame and consulting.

Another risk factor is welding the bottom flange to form a trailer chassis rail. Top flange bottom flange web. Chassis welding can pose several safety issues if the repair and procedures are is not carried out correctly and the appropriate guidelines are not followed.
