The welding jig assembly includes a body member that is planar in manner having a first end and a second end. The body member further includes a first arm member and a second arm member that are integrally formed therewith and have a void therebetween. The first arm member and the second arm member have chuck engagement rods extending outward therefrom. The welding jig assembly includes a first set of pipe elbow support members and a second set of pipe elbow support members located on opposing lateral edges of the body member. The sets of pipe elbow support members are arcuate in form and have portions extending outward from opposing sides of the body member. An aperture is formed in the body member to receive a securing chain. ## Claims ### Claim 1 A welding jig assembly comprising: a body member, said body member having a first end and a second end, said body member being planar in manner, said body member having a first lateral edge and a second lateral edge, said body member having a first arm member and a second arm member, said first arm member and said second arm member being integrally formed into said second end of said body member, said first arm member and said second arm member being angular in orientation with respect to each other;
