10 Ton Ram Repair
A Cast Steel RAM of a 10 Ton Hammer of one of our client had numerous cracks. After
initial inspection, the RAM was gouged and all cracks removed. The cracks were almost
500 mm – 600 mm deep in some places and 300 mm – 400 mm wide.

deformation of RAM due to heat cycling.
Once all the sides were restrained adequately, the RAM was preheated to 500 C in
a gas fired furnace. The RAM was later covered with Ceramic Bricks and Blanket for
proper heat Insulation. The RAM was intermittently heated with natural gas burners
to maintain the inter-pass temperature between 250-300 C.
Welding was done in stages using Crack resistant welding electrodes and Wires. The
bulk of the welding was done using welding wires to give higher productivity and
The RAM was heated through a Stress Relieving Cycle to normalize and remove all
Once the RAM returns to room temperature, it is machined by the clients.
