Can the human resources department of yongcheng city take the welder's license test?

You can't. Welder's license can only be processed after the professional qualification certification of human resources and social security departments, so the human resources department of yongcheng city cannot take the welder's license examination. Yongcheng, a county-level city under the jurisdiction of Henan Province, is managed by Shangqiu City and directly under the jurisdiction of Henan Province. It is located in the easternmost part of Henan province, at the junction of Henan, Shandong, Jiangsu and Anhui provinces.
