20. Why is it usually necessary to do welding of heavy and complex steel frame connections in a welding shop, rather than on the site of the construction?

Solution

access to specific locations and quality of welding is the main concern which makes Wielding at the shop necessary for heavy, complex and important steel structures rather than site welding. There are lot more flexibilities in shop welding as accessibility and quality of welding which can\'t be monitored properly at the site resulting in a weak point in complex structures. Hence for heavy and complex structures, shop welding is always better than site welding.
