When welding a cross country pipeline, welding is stopped by the Inspector when the weather is inclement. In Middle East wind blows continuously in month March-April. A welding tent is used during these months, solution is there. For some reason I do not to engage pipe layer to carry welding tent. My question is what velocity of wind affects the welding arc,cooling rate of welds or physics of completed weld?. API 1004 wording is "Welding shall not be done when the quality of the completed weld would be impaired by the prevailing weather condition,............ or high wind. I want a theoretical answer of wind blow in mile per hour which impairer's the weld quality? Because decision of inclement weather rest with mood of Inspector, which leads to social corruption. To determine quality of weld, X-ray will show physical impureness and not the metallurgical, then what all days production should be cut-off for test. Absurd!
