Dear Experts,
One of the manufacturer is using XL-CCH electrodes for Hard Facing Weld Overlay on c arbon steel material. (Chromium Carbide Alloy Deposit Hard Facing Electrode).
The weld overlay outer surface is showing parallel hair line cracks.
The manufacturer is arguing that these cracks are bound to develope due to inherrent properties of electrode & it is good to observe cracks on weld for ensuring the application of these type of electrode. The electrode catalogue also states that cracks can be developed on weld surface.
My question is which code/standard allow cracks on such hard facing overlay ?
