The invention relates to the technical field of mobile phone preparation, and specifically relates to a welding fixture. The welding fixture comprise a main body, a plurality of placement grooves used for placing to-be-welded objects and matched with the to-be-welded objects are formed in the main body, and a pressing plate used for limiting the to-be-welded objects after the to-be-welded objects are placed in the placement grooves is arranged on the main body. When a daughter is welded on a parent, the parent can be accurately located, thereby improving the welding accuracy, and in a welding process of a circuit board, the welding accuracy is also improved, so the final quality of a product is improved; the problem that the daughter and the parent are prone to excursion in the welding process is avoided, and meanwhile the welding efficiency is also improved; and meanwhile the welding fixture can avoid unnecessary damage to the parent, such as the circuit board, in the welding process.
