Welding with 7018 rods can be challenging, especially when they start sticking during operation. This issue not only affects the quality of the weld but also disrupts workflow. Understanding the underlying causes and solutions can help welders achieve more efficient results.

Key Takeaways

– 7018 rods are prone to sticking due to improper technique or settings.
– Correct amperage and angle can reduce sticking.
– Proper rod storage is crucial for optimal performance.
– Using the right equipment can significantly improve weld quality.

Problem / Context

Sticking occurs when the electrode fuses to the workpiece, interrupting the arc and making it difficult to complete the weld. This is a common issue with 7018 rods, which require precise conditions to function correctly.

Causes

Low Amperage

– Inadequate amperage fails to sustain the arc, causing the rod to stick.

Incorrect Angle

– Holding the rod at an incorrect angle reduces arc stability.

Poor Rod Condition

– Moisture absorption in 7018 rods can lead to sticking.

Fixes

Step 1: Adjust Amperage

– Increase Amperage: Slowly increase amperage until the arc is stable and the rod flows smoothly without sticking.

Step 2: Correct Angle

– Maintain a 10-15 Degree Angle: Keep the rod at a consistent angle to ensure smooth arc movement.

Step 3: Ensure Dry Storage

– Proper Storage: Store rods in a dry, sealed container or rod oven to prevent moisture absorption.

Step 4: Consistent Movement

– Steady Motion: Employ a steady, consistent movement along the weld joint to reduce sticking.

FAQ

What amperage should be used for 7018 rods?

Amperage settings typically range from 90 to 160 amps, depending on the rod diameter. Adjust based on welding parameters and practice.

How should 7018 rods be stored?

Store in a temperature-controlled rod oven at 250°F (121°C) to keep them dry and prevent moisture absorption.

Can rod sticking damage my welding machine?

Prolonged sticking can overheat and damage your welding machine, so it’s vital to address issues promptly.
