The invention provides a high-temperature strain gauge lead welding protection method. The high-temperature strain gauge lead welding protection method comprises a high-temperature strain gauge and measuring wire welding installation process and a lead protection process. The special wire welding head and the welding process are used, so that the welding quality can be effectively improved; an S-shaped wiring path is adopted, so that the protection on the lead is more reliable, and larger centrifugal force and airflow impact can be borne; the welding quality is improved, the lead is effectively protected, and the lead can survive for a longer time under severe test conditions. 本发明提供了一种高温应变计引线焊接防护方法，包括高温应变计与测量导线焊接安装工艺和引线防护工艺。本发明使用专用导线焊接头及本焊接工艺，可有效提高焊接质量；采用S型走线路径，对引线的防护更可靠，可承受更大的离心力和气流冲击；提高焊接质量，对引线进行有效防护，可使引线在恶劣试验条件下更长时间存活。
