Investment mold precision casting furnace plate

There are many places where stainless steel clad sand casting is needed in industry, but welding operations are not allowed because some goods do not meet the requirements. If you insist on the operation, it will only lead to quality problems of the workpiece. In order to prevent the seriousness of the problem, we should fully grasp the conditions of stainless steel castings can not be welded, and then select the processing process in a targeted manner.

In the premise of not meeting the requirements, the customer's requirements for the accuracy of stainless steel castings are very high, the investment casting joints can not be welded. For example, some areas in the drawings clearly specify that they can not be welded. There is another situation, that is, the quality of the stainless steel casting itself, not welding, including the casting test pressure leakage; surface honeycomb holes, etc., can not guarantee the quality of the casting after welding.

In addition, if a location has been welded, can not be welded again, will affect the quality of stainless steel castings, and even its application effect. Remember the above requirements, when encountered, be careful to solve.
