大型结构件焊接加工详情：大型结构件焊接加工http://www.tiandubang.com/products-detail.asp?cpid=59 金属结构件焊接加工是一个局部的迅速加热和冷却过程，焊接区由于受到四周工件本体的拘束而不能自由膨胀和收缩，冷却后在焊件中便产生焊接应力和变形。重要产品焊后都需要消除焊接应力，矫正焊接变形。大型结构件焊接加工用到的现代焊接技术已能焊出无内外缺陷的、机械性能等于甚至高于被连接体的焊缝。被焊接体在空间的相互位置称为焊接接头，接头处的强度除受焊缝质量影响外，还与其几何形状、尺寸、受力情况和工作条件等有关。接头的基本形式有对接、搭接、丁字接（正交接)和角接等。
