Provided is connection fitting and method. The connection fitting is to connect each of two connection portions of a two-electrode-integrated welding torch unit to each of two attachment ports of a shock sensor unit while fixed to the connection portion using tubular fastening parts, comprising: a tubular fitting body including a first end to be connected to the unit and a second end having a spherical shaft-shaped connection portion with first and second partial spherical surfaces to be connected to the connection portion; a first bearing member having a first sliding surface slidable against the first partial spherical surface; a second bearing member having a second sliding surface slidable against the second partial spherical surface. The second bearing member has a sliding contact portion having an outer diameter smaller than an inner diameter of the fastening parts and adapted to slidably contact an end surface of the connection portion.
