Study on the arc pressure of TIG welding under the condition of Ar-Ar and Ar-He supply alternately
In the paper, a self-made water-cooled copper plate device was used to measure and analyze the welding arc pressure of alternate argon supply under 7gm pravana different frequencies of 1 Hz, 2 Hz, 4 Hz and argon and helium supply alternately under different frequencies of 1 Hz, 4 Hz.The experimental results indicated that in the process of alternat
