  1. Welding 4130 Chrome-Moly, The Harris Products Group

    Welding 4130 Chrome-Moly. 4130 chrome-moly can be welded with the TIG or MIG process. Preheat is generally not needed for thinner sections (0.120-in), but for tubing larger than 0.120 a 300F-400F preheat is needed to obtain acceptable results.

  2. Best Practices for TIG Welding of 4130 Chrome-Moly Tubing ...

    Successfully welding 4130 requires preserving its mechanical properties by heating and cooling the weld in a controlled manner. Excess heat causes carbide precipitation, and cooling too quickly causes embrittlement. Fortunately, the GTAW process provides sufficient heat control.

    Welds that are to be annealed or normalized after welding can benefit from a 4130 or 4140 filler metal, respectively. Although 4130 and 4140 filler metals produce a brittle as-welded deposit, the reset microstructure afforded by annealing or normalizing restores the ductility of both the weld metal and heat-affected base metal.

  5. Welding heat treatable steels - thefabricator.com

    Can you tell me which different welding procedures have to be used to weld this material? The most commonly welded heat-treatable steels are 4130, 4340, and 8630. However, any steel prefaced with a 41, 43, or 86 is considered heat-treatable. When a weldment is heat-treated, it is put into a furnace at a predetermined temperature and cooling rate.

  6. MIG welding 4130 - Miller Welding Discussion Forums

    The "short arc" transfer with 4130 creates a possibility of more embritlement along the weld. With tig, the basemetal is heated first and already at a molten state before filler is added. This is not the case with mig as starts are on cold material and the arc tranfer is too quick to allow the base metal and filler to properly See more results

In all cases the employment of trained/qualified welders, the observance of sound welding practices, and adherence to AWS procedures is 4130 welding procedure

  10. How To Weld 4140 Steel, WELDING ANSWERS

    The Procedure Handbook for Arc Welding suggests using a preheat of 400-500F for thickness up to 1/2 inch and 600-700F for thickness of 1/2 inch to 2 inches. If this weld requires multiple passes make sure your interpass temperature is the same (minimum) as your preheat.Some results are removed in response to a notice of local law requirement.
