Final answer:
Flux core welding is used for shield-less welding, reducing spatter and increasing productivity.
Explanation:
Flux core welding is primarily used to weld without shielding gas, making it ideal for outdoor welding where wind can blow away the gas. This method is popular for field work and construction sites.
Another advantage of flux core welding is to reduce spatter during the welding process, resulting in cleaner welds. This technique is efficient in improving productivity and reducing post-weld cleanup.
Despite some drawbacks like increased smoke and fumes, flux core welding remains a preferred choice for its versatility in various welding situations.
