Abstract: A self-propagating high-temperature synthesis (SHS) welding-pen that can weld steel workpiece from 6 to 10 mm is developed and welds the Q235 steel. The structure and properties of the welding joint are studied. The result indicates that this type of welding is melting and the fusion zone is clear. The tensile-strength of the welding joint is 283 MPa, flexural strength is 628 MPa, impact toughness is 46.43 J·cm, and the microhardness of the welding joint and fusion zone are 230 HV and 255.6€HV, respectively. The mircohardness of the fusion zone and the welding line are higher than that of the matrix.
