The technology of large spot Nd:YAG laser-MAG hybrid welding was studied by adjusting the welding parameters. Results showed that in some welding condition compared with MAG welding the large spot Nd:YAG laser-MAG hybrid welding could also increase the depth of penetration and enhance the stability of the welding process. Within appropriate welding speed and welding current, large spot Nd:YAG laser-MAG hybrid welding could improve appearance and spreadability of the weld .
