Check the bevel angle before welding, blunt edge, gap and export volume Nanping steel corridor wrong price, within the groove and on both sides of rust, oil, iron oxide, etc. should be cleaned. 2. Preheating. Before welding, gas welding or special roast gun in the groove of the base material and both sides of the 100mm-wide uniform heating, and with a surface thermometer to measure the temperature, to prevent the surface temperature does not meet the requirements or partial oxidation, the preheating temperature. 3. Recheck preheat temperature, as temperature is not enough to be reheated Longhai Steel Corridor brand to meet the requirements.
