Continuing with the hood scoop fabrication, in this segment we will focus on fitting the scoop onto the hood and welding it up.
Before attaching the scoop to the hood, I start by welding the sides to the top. For this, I choose to use the TIG welding method, which allows me to manipulate the shape if needed later. Compared to MIG welding, TIG welding produces a softer and more ductile weld, making it an excellent choice for this application. Additionally, using TIG welding reduces the amount of grinding and clean up needed, which is always a bonus.
I begin by belt sanding off my MIG tacks from the joint. Then, I tack every 10 to 15 millimetres using TIG welding and a piece of 0.8mm MIG wire cut off the roll. Afterwards, I give it a good planish to relax the material. It’s essential to have relaxed material before welding to minimise warpage.
