7. Welding

 AISI 1045 steel is readily welded when correct procedure is followed.

Welding AISI 1045 steel in through-hardened, tempered and flame or induction hardened condition is not recommended.

Low hydrogen electrodes are preferred for welding AISI 1045 steel.

The workpiece is

• Pre-heated at 200°C–300°C (392°F - 572°F)
• Maintained at the same temperature during welding
• Cooled slowly using sand, ashes etc and
• Stress relieved at 550°C - 660°C (1022°F - 1220°F).

9.Heat Treatment

Annealing

Heat to 800°C-850°C hold until temperature is uniform throughout the section,and cool in furnace.

Hardening

Heat to 800°C-850°C hold until temperature is uniform throughout the section,soak for 10-15 minutes per 25mm of section,and quench in water or brine.
or:

Heat to 830°C -860°C soak as above and quench in oil.Temper immediately while still hand warm.

Tempering

Re heat to 400°C-650°C as required,hold until temperature is uniform throughout the section,soak for 1 hour per 25mm of section,and cool in still air.
