Horizontal TIG welding on stainless steel l**e oil pipe for a power generation turbine bearing.
A tight space and a challenging angle—welding on top of a short T-joint, right next to a large pipe.

Limited line of sight, tight clearances surrounded by obstruction piping, and a gap under the structural column of just 10 cm—smaller than the distance from your eyes to the top of your head! Welder's point of view on this stainless steel root pass for a turbine bearing l**e oil pipe. With zero direct visibility, you're leaning your head sideways, working half-blind, and relying entirely on arc feel and heat control. How do you handle restricted-access welds like this on your job site? Let me know in the comments! ⁠ ⁠ ⁠ ⁠ ⁠ ⁠ ⁠ ⁠ ⁠

Field pipe welding requires adaptability and high-level control to handle restricted spaces, awkward body angles, and blind spots. Field TIG welding on stainless pipe. Navigating tight clearance and limited visibility. Full process from root to capping pass—no extra grinding at tie-ins.

TIG welding 0Cr18Ni9 stainless steel pipe 273mm diameter 8mm wall thickness with uneven gap on site. The fit up gap varies from tight areas to sections fitting a welding rod and extreme gaps wide enough for a 100mm grinding disc. Welding position is heavily obstructed by a concrete column. Strictly zero grinding wheel used during the root pass. Gas purging process is highly optimized by using only one single argon purging cylinder and one welding gas cylinder for the entire joint. Regardless of the varying gap sizes, the internal root bead remains completely uniform in width and pe*******on throughout the entire seam. What do you think about this root pass?

A simple trick for a smooth stainless steel root pass. Always fold back the purge tape edge before feeding your filler rod. If you insert the rod straight through the middle of the tape without folding it, as soon as you tilt the rod, the adhesive will stick to the filler rod and make it very difficult to feed smoothly. Doing this prevents the inner glue from gripping your rod and creates a steady rest for your hand. What current do you usually run for this type of stainless root pass? I am setting it at 90A here.

L**e oil piping for turbine systems requires absolute cleanliness—zero grinding allowed during the root pass to avoid contamination. Here is the complete root pass process, showcasing a clean, uniform inside bead with raw welding skill only! ⁠ ⁠

Strict Spec: No Grinding on Root Pass! 🚫⚙️
Oil pipe standards prohibit grinding or re-work on the root pass to keep the inside 100% clean. Using bridge tabs snapped off with a wrench instead! 🛠️

My technique for a clean and uniform weld bead from root pass to cap pass

This is how I do the tie-in at the 9:30 position on the boiler tube assembly, with absolutely no grinding on the joint end." ⁠ ⁠ ⁠ #⁠sinhboilerturbinewelding
