Re: [MW:35350] Cast-iron welding

By Materials & Welding
Proper metallurgical answer: don't weld

If one needs to weld anyway, then are 2 options:

1) High preheat 500 - 700 degrees centigrade, preferred in a furnace, welding with Acetylene Oxygen flame with special cast iron welding bars, slow cooling afterwards, risk of size tolerance issues

2) Cold, low input 2.5 mm SMAW process, with hammering the hot weld metal to reduce thermal stress in the HAZ , risk of cracking

Keep in mind that risk of failure is large

Good luck

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
