关于焊接的几个问题？ 1. 罐底部每张钢板的下表面涂刷两遍环氧树脂沥青漆，但周边焊缝处留出50mm不予涂刷。the lower surface of each steel plate at the bottom of the tank needs to brush epoxide resin asphalt lac twice; about 50mm around the circumjacent weld shall be not brushed. 2. 罐底板任意两个相邻焊缝之间的距离，以及边缘板焊缝距底圈罐壁板纵焊缝的距离均不小于300mm。 the distance of any two adjacent weld seam and that of margin plate weld seam and bottom wall vertical welding shall be both not less than 300mm. 3. 所有罐壁开口应避开罐壁焊缝，开口接管或补强圈边缘距罐壁焊缝应大于100mm。 all wall nozzle should be avoided wall welding. the distance from nozzle or reinforcing ring margin to the wall welding shall be more than 100mm. 4. 包边角钢、罐壁加强圈自身的对接焊缝必须全焊透全溶合 the butt welding of edged-plate angle steel and wall reinforcing ring must be full penetration and full fusion. 试着翻译了一下，大家帮看看。谢谢。查看更多
