Hi Eyup,
You need to demagnetise the joint, first measure the magnetic field intensity and plan accordingly. You can use AC from your welding machine if a proper set up to demagnetise is not readily available.

I hope attached sketch will help you to understand how to coil apply for demagnetizing.

If you notice an increase in magnetism, change the direction of the coil or reverse polarity. The direction of the magnetic field will be in accordance with the rule of right hand.

Wrap weld cable around the pipe and start welding.
By this magney field will be reduced.On 18 Jun 2014 09:49, "Pratik Kshirsagar" <pratikshir@gmail.com> wrote:--Dear GV,
Generally welding can be done defect free at a magnetic field of 20G. Secondly if using GTAW, 10G creates problem in arc stability. So check with the magnetic strength and the process.
Magnetism can be minimised by any of the method;
1. Using demagnetizer available in market.
2. By creating magnetic field in opposite direction that of current magnet by passing current through coil.
Hope I have answered your query.
