A method for joining two metallic, tubular joining members to one another, the method including arranging two metallic, tubular joining members with respect to one another in an overlapping or end-face manner, and joining the joining members by material bond along a joining zone of the joining members. In the joining, a chain of joining spots extending in the circumferential direction of the joining members is produced in the joining zone, wherein successive joining spots in the chain overlap, wherein, in the joining, the joining spots are produced by means of TIG pulse welding with an arc time of up to 100 ms, preferably of up to 50 ms, wherein an arc of a welding pulse of the TIG pulse welding is extinguished after the arc time has been reached. A corresponding welding apparatus is also described.
