Summary of "Tips How to Pass a 1G Stick Test"
Key Welding Strategies and Tips for Passing a 1G Stick Test
- Preparation and Setup:
- Use a 3x6 inch A36 steel plate with a 22.5° bevel on each side for a 45° included angle.
- Maintain a root opening of about 1/4 to 5/16 inch.
- Use a backing strip (1 inch wide by 1/4 inch thick for destructive tests; wider backing required for radiograph tests).
- Clean mill scale off the backing strip and plate edges before welding.
- Use SMAW E7018 electrodes (e.g., eSAB 70 18-1 prime rods recommended for smooth arc starts).
- Welding Sequence and Technique:
- Plan a multi-pass welding sequence:
- Root pass: burn edges and melt into backing strip.
- Fill passes: multiple passes to build up weld metal, maintaining 50% coverage overlap.
- Cap passes: three bead cap to finish, ensuring about 1/8 inch reinforcement.
- Use a 90° work angle and a 10° travel angle.
- Practice intentional stop and start techniques at the root pass to demonstrate control.
- Alternate restart points to avoid stacking stops in one area.
- Use a slight oscillation if the gap is larger to ensure full fusion.
- Maintain a consistent arc length and travel speed to avoid undercut and excessive buildup.
- Plan a multi-pass welding sequence:
- Visual Aids and Quality Control:
- Use soapstone to mark the toe of the previous weld pass to guide electrode placement.
- Draw travel speed indicators to maintain consistent puddle coverage.
- Ensure weld bead is flat and uniform with no lack of fusion or porosity.
- Keep reinforcement flush to 1/8 inch maximum.
- Check for and avoid undercutting by controlling arc length and travel speed.
- Use run-on and run-off tabs on either side of the weld to ensure smooth start and finish.
- Additional Tips:
- Rotate or flip the plate to even out weld height.
- Don’t rush the weld; slow and steady travel speed is key.
- If visibility is poor, adjust your head position to better see the weld puddle.
- Clean slag between passes but avoid over-cleaning that might damage the weld.
- Practice stop/start and restarts frequently to build confidence.
- Product Recommendation:
- eSAB 70 18-1 prime welding rods are highlighted for their excellent arc initiation and smooth weld characteristics.
- Community Engagement:
- Viewers are encouraged to share their own tips or words of wisdom in the comments to help others overcome test anxiety and improve technique.
